Description

Technical Field

[0001] This utility model relates to the field of booster pump technology, and in particular to a high-pressure chamber damping device for an RO pump. Background Technology

[0002] RO pumps, short for reverse osmosis booster pumps, are the core booster equipment in reverse osmosis water treatment systems. Their core function is to provide sufficient pressure to the RO membrane, enabling water molecules to penetrate the membrane for purification, while simultaneously removing impurities (such as inorganic salts, heavy metals, and microorganisms). They are widely used in seawater desalination, household water purification, and industrial water treatment. However, existing RO pumps are prone to generating high-pressure impact vibrations in the drainage chamber during drainage, increasing the vibration of the pump head and casing and generating significant noise. Therefore, it is necessary to design a new type of RO pump vibration damping structure to solve these problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a shock absorption device for the high-pressure chamber of an RO pump. An elastic plastic is provided in the drainage chamber, and the elastic plastic is connected to the drainage chamber through a compression spring. When the water flows into the drainage chamber by opening the drainage valve, the water flows into contact with the elastic plastic and drives the elastic plastic to compress the compression spring. This allows the elastic plastic and the compression spring to work together to buffer the impact of the water flow on the drainage chamber, avoiding direct impact of the water flow on the drainage chamber and reducing the vibration and noise caused by the impact on the drainage chamber.

[0004] A high-pressure chamber vibration damping device for an RO pump includes a pump casing and a pump head. A drainage chamber is provided in the middle of the inner side of the pump casing. An output pipe is provided on the side wall of the pump casing and communicates with the drainage chamber. A drainage valve is provided in the center of the pump head. A mounting column is provided in the middle of the drainage chamber. An elastic plastic is slidably connected to the mounting column and is connected to the top surface of the drainage chamber through a compression spring.

[0005] Preferably, the side wall of the pump casing is provided with an input pipe head, the input pipe head extends into the pump casing, the side wall of the drainage chamber is provided with an output hole at the position corresponding to the output pipe head, the pump casing and the pump head are connected to form a water inlet chamber, and the input pipe head communicates with the water inlet chamber.

[0006] Preferably, the pump head has a plurality of drainage holes at its center, and the drainage valve plate covers the plurality of drainage holes, and the pump head has a plurality of water inlet holes around the drainage valve plate.

[0007] Preferably, the mounting post has a mounting hole at its center, and the mounting hole is threadedly connected to a limit nut; the elastic plastic has a sliding hole at its center, and the sliding hole of the elastic plastic is slidably connected to the mounting post.

[0008] Preferably, the top surface of the drainage cavity is provided with a supporting protrusion, the elastic plastic is provided with an arc-shaped opening, and the bottom surface of the elastic plastic is provided with multiple elastic protrusions.

[0009] The beneficial effects of this utility model are as follows: The high-pressure chamber shock absorption device of the RO pump works together with the pump casing and the pump head to provide an elastic plastic in the drainage chamber. The elastic plastic is connected to the drainage chamber through a compression spring. When the water flows into the drainage chamber after opening the drainage valve, the water comes into contact with the elastic plastic and drives the elastic plastic to compress the compression spring. This allows the elastic plastic and the compression spring to work together to buffer the impact of the water flow on the drainage chamber, preventing the water flow from directly impacting the drainage chamber and reducing the vibration and noise caused by the impact on the drainage chamber.

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0013] like Figures 1 to 5 As shown, a high-pressure chamber vibration damping device for an RO pump includes a pump housing 1 and a pump head 2. A drainage chamber 3 is provided in the middle of the inner side of the pump housing 1. An output pipe head 4 is provided on the side wall of the pump housing 1, and the output pipe head 4 communicates with the drainage chamber 3. A drainage valve plate 5 is provided in the center of the pump head 2. A mounting post 6 is provided in the middle of the drainage chamber 3. An elastic plastic 7 is slidably connected to the mounting post 6, and the elastic plastic 7 is connected to the top surface of the drainage chamber 3 through a compression spring 8.

[0014] The working principle of the high-pressure chamber damping device of the RO pump described in this utility model is achieved through the cooperation of the pump casing 11 and the pump head 22. Figures 1 to 5 As shown, an elastic plastic 7 is installed inside the drainage chamber 3. The elastic plastic 7 is connected to the drainage chamber 3 through a compression spring 8. When the water flows into the drainage chamber 3 after opening the drainage valve plate 5, the water flows into contact with the elastic plastic 7 and causes the elastic plastic 7 to compress the compression spring 8. This allows the elastic plastic 7 and the compression spring 8 to work together to buffer the impact of the water flow on the drainage chamber 3. Compared with traditional booster pumps, the high-pressure chamber shock absorption device of this RO pump can prevent the water flow from directly impacting the drainage chamber 3 and reduce the vibration and noise generated by the impact on the drainage chamber 3.

[0015] Specifically, the pump casing 1 has an input pipe 9 on its side wall, which extends into the pump casing 1. The drain chamber 3 has an output hole 10 on its side wall corresponding to the output pipe 4. The pump casing 1 and pump head 2 are connected to form a water inlet chamber 11, and the input pipe 9 communicates with the water inlet chamber 11. The pump head 2 has multiple drain holes 12 at its center, and a drain valve plate 5 covers these drain holes 12. The pump head 2 also has multiple water inlet holes 13 around the drain valve plate 5. Figures 1 to 5 As shown, water flows along the input pipe 9 to the inlet chamber 11 formed by the pump casing 1 and the pump head 2. Then, the water flows into the pump head 2 through the inlet hole 13. The drain valve plate 5 is slidably connected to the pump head 2 and blocks the drain hole 12. Then, the water flows out from the pump head 2 and drives the drain valve plate 5 to open upward so that the water flows into the drain chamber 3. After the water flows into the drain chamber 3, it comes into contact with the elastic plastic 7 and drives the elastic plastic 7 to compress the compression spring 8 upward. In this way, the elastic plastic 7 and the compression spring 8 work together to buffer the impact of the water flow on the drain chamber 3, which can prevent the water flow from directly impacting the drain chamber 3 and reduce the vibration and noise caused by the impact on the drain chamber 3.

[0016] Furthermore, the mounting post 6 has a mounting hole 14 at its center, and the mounting hole 14 is threadedly connected to a limit nut 15. The elastic plastic 7 has a sliding hole at its center, and the sliding hole of the elastic plastic 7 is slidably connected to the mounting post 6. Even further, the top surface of the drainage cavity 3 has a supporting protrusion 16, the elastic plastic 7 has an arc-shaped opening, and the bottom surface of the elastic plastic 7 has multiple elastic protrusions 17, such as... Figures 1 to 5As shown, the limiting nut 15 can abut against the elastic plastic 7 and prevent the elastic plastic 7 from falling off the mounting post 6. The limiting nut 15 and the mounting hole 14 are detachably connected to facilitate the disassembly and assembly of the elastic plastic 7. When the water flow drives the elastic plastic 7 to compress the compression spring 8, the elastic protrusion 17 can be made of plastic. The multiple elastic protrusions 17 of the elastic plastic 7 can disperse the water flow. The elastic plastic 7 moves upward along the mounting post 6 through the sliding hole and abuts against the support protrusion 16 of the drain cavity 3, which reduces the contact area between the elastic plastic 7 and the top surface of the drain cavity 3, and can reduce the vibration and noise caused by the impact on the drain cavity 3. After the elastic plastic 7 moves upward along the mounting post 6 through the slider, it protrudes out of the output hole 10. Finally, the water flows out along the output pipe head 4.

[0017] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
